There’s a simple work around with that. If your Pokémon stop obeying you at a certain level, that means you have to beat a gym that you’re supposed to beat. This is to prevent players from grinding their Pokémon in the starting area to lvl 100. Just tell Leo to do that.

A World where high-level Pokémon only obey the very best and brightest of people, Nobel Prize winners and such? Now wouldn't that be Onixpected and very realistic...

Shouldn't it be that he makes them leave his party after level 25?

Holy shit this is genious

I'm surprised no one has made this joke already. I mean it was right in front of us all

His Lugia is shiny, what the hell

Or he releases them at level 25 really.

And he dumps his girlfriends when they reach Level 26
